Mainland Key N springs mild upset in feature

Harry Von Knoblauch's Mainland Key N ($12.40, Ross Wolfenden) was the beneficiary of a pocket trip in Monday's harness racing $20,000 Open at Harrington Raceway and responded with a strong surge in the stretch to prevail in 1:52.

Trained by Peter Tritton, it was the fastest time of the season at Harrington. The 7-year-old Stoney Key gelding sat behind favorite and pacesetter Wind Me Up throughout fractions of 27.3, 56 and 1:24.3 before edging to the outside in the stretch and passing the leader for a one length win. Artist Point closed ground late for second as Wind Me Up held on for third.

Mainland Key N notched his 25th career win.

It was one of three winners on the card for Harrington's leading driver, Wolfenden.
